ok guys i made a breakthrough of "KFC snacker size" proportions.
OK so im hungry and not funny. but i am gaining on my pause problem.
today i found out that if i short out portc.2 it will "turn off" my solenoid "driver" the only way for the driver to turn fully off is to short it. portc.2 =0 doesnt go low enough.
secondly, i found out how the driver works. my solenoid red wire is connected to a 5+, and the black wire of the solenoid is connected to 2 transitors in parallel. one of the transiters set the sink bias to make the solenoid "driver" at a 4.4 volts on the ground side, even when portc.2 is low. and when portc.2 goes high, it sinks the solenoid over 5+. thereby fireing the solenoid.
This has led me to beliver that when i ground out the portc.2 pin, which in turn turns off the driving transistor, which turns off the solenoid.
that can only mean that when i put portc.2 = 0 it is not going low enough. how do i make portc.2 less than 0it really wierd cause as soon as i short portc.2 with my vdd goes back up to 5+.
ive tried swapping solenoids and batteries.
